摘　　要：A mutant of Candida tropicalis FYD-2 was obtained from its parental strain SFP-1186 by ultraviolet treatments.On shaking flask,the yield of mixed dicarboxylic acid(DCA) by the mutant was 21.4% higher than that by its ancestor.The amount of mixed DCA reached 156g/L for 120h incubation in a 10 L autoconrolled fermentor where the culture medium contained 25% n-paraffin.The process of induced and screening mutant was introduced and the time course of fermentation in 10 L fermentor was discussed.A mutant of Candida tropicalis FYD-2 was obtained from its parental strain SFP-1186 by ultraviolet treatments.On shaking flask,the yield of mixed dicarboxylic acid(DCA) by the mutant was 21.4% higher than that by its ancestor.The amount of mixed DCA reached 156g/L for 120h incubation in a 10 L autoconrolled fermentor where the culture medium contained 25% n-paraffin.The process of induced and screening mutant was introduced and the time course of fermentation in 10 L fermentor was discussed.
